To all 'whom .it may. concer/n.:

Be itv known that 15.-Louis TROLLE, a citi- V.zen of the UnitedStates, andv residing at Racine, in thecounty. of Racine and State of lWisconsin,.have invented anew and'lmproved Footwear, of which the following is a specification; l

rlhis invention relates to the construction of footwear such as boots and shoes and par'- ticularly to such as are intended for the use of miners, railway men, foundrymen, quarrymen, coke oven tenders, furnace men and others who walk among cinders, broken stone and other rough materials and on wet ground in which such rough materials are embedded, and its object is to provide a llanged metal bottom to resist the wear, leather or reinforced rubber uppers extending down within the side flanges of the bottom, and a marginal reinforcing strip to prevent the fasteners which secure the uppers to the bottom from being pulled through vthe uppers.

In the acompanying drawing, Figure 1 is aside elevation of a rubber boot provided with a metal bottom. Fig. 2 is a section on the line 2 2 of Fig. 1 on a larger scale. Fig. 3 is a section on the line 3-3 showing a fastener in position. Fig. 4 is a side elevation of a shoe provided with a metal bottom. Fig. 5 is a section on the line 5 5 of Fig. 4.

Similar reference characters refer to like parts throughout the several views.

The combination of a sheet metal bottom to resist wear and rubber or leather uppers, together with a removable hair-felt insole constitutes a comfortable foot covering which resists a maximum of wear. rfhese boots and shoes are warm in winter and cool in summer and the felt insoles can be taken out and washed so that the foot may be kept fresh and clean. But hitherto, the manufacturers of footwear of this character have experienced great diiiiculty in preventing the bottoms from separating from the uppers, and the solution of this diiiiculty constitutes the present invention.

The boot shown in Figs. 1, 2 and 3 comprises a metal bottom consisting of a sole 1 and side flanges 2, the uppers consisting of a layer 3 of rubber thickened along its lower edge 4 which may be provided with a layer of fibrous reinforcement 5, and theinner p i lSpecification of Letters Patent.

lining 6,- preferably a layer of fabric indu-v rated with rubber, and a strip of leather 7 which extends entirely around the bottom of the-uppers. This strip of leather is secured in position preferably by and during the vulcanizing of the rubber.

The rubber 3, lining 6 and leather 7 all extend down to the sole 15 andare secured together andV to each other by means of the fasteners 8 which extend through the side flanges 2 and the layers 3, 6 and 7 and are clenched back into these layers. By stopping the lower edges of the uppers and of the reinforcing strips at thermetal sole, all undesirable ribs and other projections are avoided while full strength is retained. The fasteners are placed so near together that the outer surface of the rubber layer 3 is closely drawn against the flanges 2 so as to render the joint water tight.

l/Vithin the foot of the boot'is an insole 10, preferably of hair-felt which spaces the foot of the wearer from the metal sole and so prevents the foot from being chilled in cold weather and from being burned when stepping on hot cinders and slag. A heel 11 of any desired character may be attached to the metal bottom.

When water-tightness is not a prime consideration, a shoe 12 may be constructed with leather uppers 13 which are reinforced at their lower edges by means of strips 14 of leather secured to the uppers by rows of vstitches 15. The bottom has the metal sole 16 with side flanges 17 to which the uppers are attached by means of the clenched fasteners 18. These uppers again extend down to the metal sole. The bottom of the shoe may be provided with an insulating block or pad 19 which may be positioned by the sheet metal holder 20, the holder being secured to the sole in any desired manner, preferably by welding. An insole 21 is again provided to insulate the foot of the wearer from the metal sole 16, and a heel 22 of any desired character may be attached to the sole.

Instead of the uppers 13 of the shoes being of leather7 they may be of heavy canvas or duck material, and the reinforcing strips 7 and 14 may also be of heavy canvas or of fiber, either in natural condition or properly treated as may be found desirable. The sizes and proportions of the various parts may all be changed by those skilled in the art :Without Ydeparting'fromV sipirit of V*my invention as Set fortliin ythe following claims.
